IMHO, the EMS SPIFR community is an accident waiting to happen. It’s hard to believe, in such a high workload environment with very little room for error, operators and the FAA do not demand overwhelming procedural standardization. Airlines have operated this way for years.
For example, an approach checklist from an EMS operator is approach-type generic, completely ignores use of automation, and lacks any specificity to actual installed avionics.
